    Abstract: Embodiments of this application provide a synchronization signal/physical broadcast channel block (SSB) measurement method and an apparatus. One example method includes that a terminal device receives first information and second information. The first information indicates a time domain position of an SSB sent by a serving cell, and the second information indicates a set of SSBs that the terminal device needs to measure and that are sent by a neighboring cell. The terminal device measures, in a first measurement window based on the first information, the SSB sent by the serving cell. The terminal device measures, in a second measurement window based on the second information, the SSB sent by the neighboring cell.

    Abstract: This application provides a transmission method and a transmission apparatus, so that a receive end can correctly demodulate data. A transmission method may include performing a phase compensation operation of a corresponding frequency value on each of m first signals in k signals, to obtain m second signals, where each of the m first signals is located at a non-center frequency of a current carrier, each first signal is a synchronization signal or data, m and k each are a positive integer, and m≤k. The method may also include performing sending processing on the m second signals.

    Abstract: A method includes selecting N cells waiting to be camped on from a candidate cell list, decoding a Physical Broadcast Channel (PBCH) of each of the selected N cells waiting to be camped on, selecting, from at least one cell whose PBCH is successfully decoded, one cell as a cell continuing waiting to be camped on, and when a remaining minimum system information (RMSI) decoding result of the cell continuing waiting to be camped on indicates that the cell continuing waiting to be camped on meets a camping criterion, determining the cell continuing waiting to be camped on as the cell to be camped on.

    Abstract: An interference cancellation method, data sending method, apparatus, user equipment and base station in a Long Term Evolution system are disclosed. The interference cancellation method includes: obtaining downlink cell-specific power ratio information of a specific cell; performing channel estimation based on a downlink cell-specific reference signal (CRS) of the specific cell, to obtain a channel estimation matrix of a specific physical channel, signal, or message of the specific cell; compensating the channel estimation matrix by using the downlink cell-specific power ratio information; and canceling, in an original signal that is received from a target cell and is interfered by the specific cell, interference caused by the specific cell in a received signal from a specific physical channel, signal, or message. A technical problem in the prior art that a user equipment cannot effectively cancel interference because power transmission strength of a strong interfering cell cannot be correctly estimated is solved.
